Further Explanation of the Cosmological Constant Problem by Discrete Space-time through Modified Holographic Principle

The author proposed in his previous papers in 2001 that the problem of the cosmological constant could be resolved and its calculated value agrees excellently with the observations by assuming that the space-time itself, as the phase of Higgs condensate, is discrete in nature. Further to such idea, a different approach involving the concept of vacuum entropy that is constrained by the modified Holographic Principle is being used in the calculation of the cosmological constant value at three different phase transition times in the early universe. It is interesting and quite unexpected that it arrives at the same conclusion as the previous approach. It therefore reveals that something fundamental is present in the theory. The problem on the preservation of Lorentz invariance in discrete space-time is also discussed.

A Theory for the Cosmological Constant and its Explanation of the Gravitational Constant

This paper continues the development of a discrete space-time concept that is recently used in the explanation of the cosmological constant. Instead of order estimation, a more theoretical treatment of the theory is introduced. Based on the discrete space-time hypothesis, we find that the electroweak theory and General Relativity can be combined into a single theory. An analytical form of the cosmological constant can be found and the weakness problem of the gravitational constant can also be explained.

A Possible Solution to the Cosmological Constant Problem By Discrete Space-time Hypothesis

The cosmological constant problem is explained by a theory based on the discrete space-time hypothesis. The calculated cosmological constant value is of the order of 10^-52[m]^-2 or equivalent to about 0.7 of the critical mass density. It is in excellent agreement with Type Ia SN observational data and recent results of BOOMERANG and MAXIMA. Our theory also implies that the quantization of the space-time metric is not necessary since it is not a fundamental field. The divergence problem of quantum gravity is then of no interest. Cosmic inflation is given out as a consequence of the theory and the universe is found to be alternatively dominated by the cosmological constant and the mass density at different cosmic time period. Our calculation also shows that the mass energy density is of similar order of magnitude as the vacuum energy density in the present universe but it is just a coincidence. This result supports the anthropic principle.

The Day-night Variation of Cosmic Rays Instensity at Sea Level Under the Influence of Meteorological Fronts and Troughs

The day-night variation of cosmic rays intensity at sea level has been observed by a simple G-M counter telescope. We preform two 5 hours counting during the day and night and find that the pattern of variation is closely related to the atmospheric disturbance, especially when the observation station is being affected by meterological front or trough. Such effects may lasts for a few days until the trough or fronts weakened. The pattern of variation may be negatively correlated to the altitude of the 0 degC level of the atmosphere. This is closely related to the muon decay effect in the atmosphere. The phenomenon should be further investigation for possible application in weather forecasting.
